PARIS, December 15. /TASS/. French law enforcers raided several places in Paris, Toulouse and Normandy on Monday to break up an Islamic network recruiting fighters worldwide as the French Interior Ministry reported a steep rise in the number of French Islamists heading for Syria and Iraq to join jihadist fighters.
Some 15 locations were said to have been stormed in the operation but no details have been given of how many people were detained.
Security service sources say about 400 French nationals have already joined Middle East radical groups such as Islamic State, and that 400 more will join soon.
Reports in November said at least two French nationals had taken part in the execution of American hostage Peter Kassig and a group of Syrian captives. One of them was identified as Maxim Oshar, 22, from Normandy.
Ethnic French, Oshar converted to Islam "at the age of reason," quickly developing radical views and leaving France to join terrorist fighters in 2013.
Sources say those leaving for trouble spots in the Middle East and then returning home are a serious concern. Security services put the number of such individuals at about 120.
